Just got the same issue after installing Developer Tools
Microsoft ASP.NET and Web Tools 2015 (Beta7). I tried to reinstall ASP.NET Project Templates but it didn’t help.
While looking into “Add / remove programs” -> “Visual 2015” -> “Modify”
, I found the “Web developer tools” unchecked. This SO answer helps me to figure this.
After reinstalling this, everything reappears
